# SEBAT54A

**SINO IC** · Schottky Diodes · SOT-23

SEBAT54A from SINO IC, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K1 | passive | Cathode of the first Schottky diode (bottom-left pin in the SEBAT54A drawing), part of a dual common-anode pair rated VR 30 V DC and IFRM 300 mA. |
| 2 | K2 | passive | Cathode of the second Schottky diode (bottom-right pin in the SEBAT54A drawing), part of a dual common-anode pair rated VR 30 V DC and IFRM 300 mA. |
| 3 | A | passive | Common anode of both Schottky diodes (top pin in the SEBAT54A drawing), with forward voltage max 320 mV at IF=1mA and reverse current max 2.0 uA at VR=25V. |

## CAD (KiCad official)

- Symbol: `SEBAT54A`
- Footprint: `Package_TO_SOT_SMD:SOT-23`
- 3D model: SOT-23 (KiCad packages3D, STEP)
- 3D model files: `sebat54a-etched.step` / `sebat54a-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sebat54a.step` / `sebat54a.glb` are the bare package body.
